517. Liability of quantity surveyor.

The quantity surveyor is usually employed to prepare bills of quantities1, to measure and value the works for the purposes of payment2, and to perform other duties. His authority may be defined by the contract3. He must prepare the bills of quantities and make his measurements and valuations skilfully, though he will not be liable if he makes a few arithmetical errors in carrying out a large number of intricate calculations4.

The quantity surveyor is not liable to the contractor for any representations contained in the bills of quantities, unless such representations are made fraudulently5, but he may be liable
